IMPROVEMENT IN GORN-PLANTERS.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, JAMES SELBY, of Peoria, in the county of Peoria, andState of Illinois, have, invented certain new and useful ImprovementsinCorn-Planters; and I do hereby declare that the following is a full,clear, and exact'description thereof, reference being had to theaccompanying drawings, making part of this specification, and to theletters of reference marked thereon, like letters indicating like partswherever they occur.

To enable others skilled in the art to construct and use my invention, Iwill proceed to describe it.

My invention consists in certain improvements in the construction andmode of operating the valves of cornplanters, as hereinafter morespecifically described.

Figure 1 is a longitudinal vertical section of a seed-hopper, with itstube and valves attached.

Figure 2 is a bottom plan view of the same.

Figure 3 is a transverse section of the seed-tube, taken on the line ata: of fig. 1.

Figure 4 is a bottom plan view of a portion of the seed-slide or uppervalve, and upper end of the lower valve-rod.

My present invention relates to that class of machines known as horse ortwo-row corn-planters, and is an improvement upon the machine heretoforepatented to me, these improvements, however, being applicable also toother machines as well as to my own.

The improvements consist, first, in an arrangement of devices foroperating the upper valve or seed-slide;

and, second, in a new arrangement of the lower valve and seed-tube, andmeans of operating the valve.

I construct the hopper A, and its bottom, E, in the manner described inmy patent of August 30, 1864, with the seed-slide 0 working between thebottom, E, and a plate, G, to the under side of which the seed-tube B isfirmly attached, as represented in fig. 1. I

From the inner side of plate G an arm, D, projects, as represented infig. 1, and upon this arm rests a friction-roller, h, attached to theunder side of the slide 0, the roller It being grooved at its centre, soas to have a flange, Z, projecting down on each side of the arm D, toserve as a guide and keep the slide from being pushed sidewise, and thusbinding inits bearings, the object being to cause the slide 0 to workfreely and easily, and prevent the usual binding and wear of the parts.It will of course be understood that this arrangement is duplicated onthe opposite side of the machine, and that thus the slide C rests on andis guided by the two grooved rollers it, running on the two rigid armsD.

The slide C is operated by a lever, L, in the usual manner, but thislever, instead of having its lower end project loosely through a mortiseor hole in the bar connecting the two slides C, has a pin, 01, passingtransversely through its lower end, which pin rests in notches in theupper face of aprojecting lug, 6, attached to the slide 0, as shown infig. 1. The lever L is fulcrumed by a similar pin, 25, to another lug orar1n,-a, secured to the inner top side of the hopper A; 'Bythis'arrangement, when the lever L is operated to move the slide G, thelatter will be kept pressed down on the arm D, instead of being raisedmore or less, as it is apt to be when the lever work's loosely in a holein the slide, or the bar connecting the two slides at opposite sides ofthe machine, and thus it is made to work more easily, and without thebinding ellect usualin this class of machines.

The seed-tube B is made rectangular in cross-section, as represented infig. 3, andit is divided by avertical partition, I, into two separatecompartments or tubes, which extend from the under side of the.plate Gdown to a transverse partition, f, located near its lower end, as shownin fig. 1, the two tubes being so arranged that the seed is delivered bythe slide 0 alternately into one and the bther.

The partition I does not extend entirely across the tube B, but stopsshort at one side, thus leaving a small space, in which is located arod, 6, as shown in figs. 1 and 2. At its lower end this rod isjournalled in the horizontal partitionf, through which it extends, andhas a valve, n, secured to its lower end, directly under the partitionf; this valve n being arranged to swing so as to close alternately theholes 0 made through this partitionj, these holes being arranged, one oneach side of the partition I, as shown in figs. 2 and 3. The upper endof the r'od1b"is bent in the form of a crank, c, as shown in fig. 1, andhas its point fitting in arecess, e,

. the form of which is more clearly shown in fig. 4, this recess, e,being formed in the under side of'tlic-slide C.

Bythis arrangement, every time the slide 0 is moved either way, thewalls or sides of the recess 0, in the under side of the slide 0, strikeagainst the crank c, and turn the rod b, and thereby operate the valven. The slide, with its seed-cells z, is so arranged that while the seedis dropped from the hopper into one of the compartments in tube B, thevalve n is so moved as to open the hole aim the 'other compartment, andpermit the seed previously deposited therein to fall into thefurrowbelow.

By these improvements I add greatly to the eificienoyof the machine, andthe ease with which it can be operated.

Having thus described my invention, what I claim, is-

1,The combination, with the slide 0, of the roller h and arm or supportD, when arranged to operate substantially as described. v

2 The lever L, having its lower end resting in a socket or restconnected to the seed'slide, for the purpose of holding the slide downwhile operating it, as set forth. I r

3. The seed-tube 13, provided with the vertical partition I andhorizontal partition f, with the holes otherein, substantially asdescribed. g

4. The valve-rod b,' with the valve n attached thereto, said rod 6 beinglocated in the seed-tube B, and operated by the slide 0, substantiallyas shown and described.
